XXX本科毕业设计（论文）CA6140杠杆加工工艺及夹具设计学生姓名学生学号院（系）机电工程学院年级专业03级机械设计制造及其自动化指导教师副教授二七年六月XXXA1A0A2A3A4A5A7A8I摘要本设计是CA6140杠杆零件的加工工艺规程及一些工序的专用夹具设计。CA6140杠杆零件的主要加工表面是平面及孔。一般来说，保证平面的加工精度要比保证孔的加工精度容易。因此，本设计遵循先面后孔的原则。并将孔与平面的加工明确划分成粗加工和精加工阶段以保证孔的加工精度。基准的选择以杠杆45外圆面作为粗基准，以25孔及其下表面作为精基准。先将底面加工出来，然后作为定位基准，在以底面作为精基准加工孔。整个加工过程选用组合机床。在夹具方面选用专用夹具。考虑到零件的结构尺寸简单，夹紧方式多采用手动夹紧，夹紧简单，机构设计简单，且能满足设计要求。关键词杠杆零件，加工工艺，夹具，定位，夹紧XXXA1A0A2A3A4A5ABSTRACTIIABSTRACTTHISPAPERISTODESIGNTHECRAFTPROCESSESOFMAKINGTHECA6140LEVERSPAREPARTSANDSOMESPECIALIZEDTONGSINTHEPROCESSTHECA6140LEVERSPAREPARTPRIMARILYPROCESSESTHESURFACEANDBORESGENERALLYSPEAKING,TOGUARANTEETHEACCURACYOFTHEFLATSURFACEPROCESSISEASIERTHANTHATOFTHEBORETHEREFORE,THISDESIGNFOLLOWSTHEPRINCIPLETHATSURFACEFIRSTANDTHENTHEBORE,ANDDEFINITELYDIVIDESTHEPROCESSOFFLATSURFACEANDBOREINTOCOARSEPROCESSESANDPRECISEPROCESSESTOGUARANTEETHEBOREPROCESSESTHEBASICCHOICEISTOCONSIDER45OUTSIDECIRCLEASROUGHBASISANDTOCONSIDER25BOREANDITSNEXTSURFACEASPRECISEBASISTHEBOTTOMISFIRSTPROCESSEDOUTTOBEFIXEDPOSITIONBASIS,ANDPROCESSTHEBOREUSINGTHEBOTTOMASTHEPRECISEBASISTHEWHOLEPROCESSESCHOOSETHEMACHINEBEDINTHEASPECTSOFTONGSCHOOSING,SPECIALIZEDTONGSAREUSEDINCONSIDERATIONOFTHESIMPLECONSTRUCTIONSIZEOFTHESPAREPARTS,CLIPPINGBYHANDSISADOPTEDITISSIMPLE,ANDTHEORGANIZATIONDESIGNISSIMPLE,ANDCANSATISFYTHEDESIGNREQUESTKEYWORDSLEVERSPAREPARTS,CRAFTPROCES,TONGS,FIXEDPOSITION,TIGHTCLIPXXXA6A9A10A11A12A13A14A151摘要A16ABSTRSCTA171绪论1A18A19A18A20A21A22A23A24A25A26A27A28A21A22A23A24A26A271A29A30A31A32A33A34A35A36A37A38A24A39A40A41A42A34A35A36A37A40A4112杠杆加工工艺规程设计3A31A30A29A43A44A34A45A46A45A463A47A48A49A48A49A50A51A52A53A543A47A48A49A48A47A50A51A52A55A56A57A583A31A30A31A59A60A61A62A34A63A64A65A21A66A62A67A68A69A39A40A70A71A72A73A34A74A71A75A76A60A61A64A65A62A67A71A754A47A48A47A48A49A77A78A79A80A52A81A82A83A844A47A48A47A48A47A85A86A52A87A884A47A48A47A48A89A77A78A55A56A90A914A47A48A47A48A92A93A94A95A55A96A97A98A55A99A100A101A102A79A80A100A101A52A77A785A47A48A47A48A103A77A78A104A105A54A976A47A48A47A48A106A77A78A85A107A55A10817A31A30A109A110A37233专用夹具设计24A109A30A29A61A62A62A67A111A62A67A112A31A113A32A33A39A4024A89A48A49A48A49A78A114A85A115A52A87A8824A89A48A49A48A47A104A105A116A52A117A118A119A120A121A116A57A5824A89A48A49A48A89A120A121A122A51A102A123A116A124A125A77A7825A89A48A49A48A92A126A127A98A128A127A98A126A129A130A102A120A131A132A133A11726A89A48A49A48A103A120A131A134A135A57A5827A89A48A49A48A106A120A131A133A117A102A136A53A52A137A138A139A14027A109A30A31A141A142A143A144A145A146A142A143A144A145A109A147A148A148A34A149A150A151A32A33A39A40A150A15128A89A48A47A48A49A78A114A85A115A52A87A8828A89A48A47A48A47A78A114A122A51A52A133A11728A89A48A47A48A89A78A114A152A153A57A5829A89A48A47A48A92A154A105A116A119A120A121A116A117A11829A89A48A47A48A103A120A131A132A155A83A119A156A157A124A125A133A11730A89A48A47A48A106A120A121A124A125A102A120A131A132A133A11734XXXA107A158A159A160A133A117A161A1622A89A48A47A48A163A120A131A133A117A102A136A53A52A137A138A139A14035A109A30A109A164A165A166A167A168A111A32A33A39A4035A89A48A89A48A49A78A114A85A115A52A87A8835A89A48A89A48A47A78A114A122A51A52A133A11735A89A48A89A48A89A78A114A152A153A57A5836A89A48A89A48A92A126A105A116A119A120A121A116A52A117A11837A89A48A89A48A103A126A127A98A128A127A98A126A129A130A102A120A131A132A133A11737A89A48A89A48A106A120A121A124A125A52A133A11738A89A48A89A48A163A120A131A133A117A102A136A53A52A137A138A139A14038A109A30A169A110A37394总结40参考文献41致谢42XXXA170A171A172A173A174A1751A176A17711绪论加工工艺及夹具毕业设计是对所学专业知识的一次巩固，是在进行社会实G17353G1055G2081对所学G2520G16850程的一次G9157G1849的G13520合G5627的G5647G3809G1076，G1075是G10714G16782G13864G13007实G19481的G16769G13463。机床夹具G5062成为机G7812加工G1025的G18337要G16025G3803。机床夹具的设计和G1363用是G1431进G10995G1147G2469G4649的G18337要工艺G6526G7057G1055一。G19555G11540G6117G3281机G7812工业G10995G1147的G993G7041G2469G4649G15机床夹具的G6925进和G2031G17908G5062成为G5203G3835机G7812工G1166和G6228G7427G1166G2604在G6228G7427G19773G7044G1025的一G20045G18337要G1231G2165。11课题背景及发展趋势G7460G7021G451结构G451工艺是G1147G2709设计的G10301G17148G6228G7427基G11796，一方面，G6228G7427G2058G13434G11540设计G727G2490一方面，G6228G7427G1075G6524动G11540设计。G1186设计G13666学的G16278G9869G11487，G6228G7427G993G1177G1177是G10301G17148基G11796G17836具G7389其本G17535的G256G2163能G257作用，G2494要G2904G1122G5224用G7460G7021的G10317G5627，G1116以G11468G5224的结构G5430式和G17878G5415的加工工艺，G4613能G3827G2031G17908出实用，G13666G16278，G13475G8994的G1147G2709，G2375在G1147G2709G1025G2469G6393G6228G7427G9520在的G256G2163能G257。G6228G7427是G1147G2709G5430G5589G2469G4649的先G4560，G7044G7460G7021，G7044工艺的出G10628，G5529然G13485G1147G2709G5114来G7044的结构，G7044的G5430G5589和G7044的G17908G3423G20130G7696。G7460G7021，加工工艺，结构，G1147G2709G5430G16949G7389机G3332G13864G13007在一G17227的，G7588个G10627G14422的G2476G19773，G1427会G5353G17227整个机G1319的G2476G2282。工业的G17817G17907G2469G4649，对G1147G2709的G2709G12193和G10995G1147G10587G6564出G1114G5852来G5852G20652的要求，G1363多G2709G12193，对G1025G4579G6221G10995G1147作为机G7812G10995G1147的主G8981，为G1114G17878G5224机G7812G10995G1147的这G12193G2469G4649趋势，G5529然对机床夹具G6564出更G20652的要求。12夹具的基本结构及夹具设计的内容按在夹具G1025的作用G15G3332位结构G10317G9869G15组成夹具的元件可以划分为以下几类1定位元件及定位
